ROADWAY REINFORCEMENT.

To all whom it may concern:

Be it known that I, (i'rsonon W. lVARMo'rH, a citizen of the UnitedStates, and a resident of Indianapolis, county of Marion, and State ofIndiana, have invented a certain new and useful Roadway Reinforcement;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings inwhich like letters refer to like parts.

The object of this invention is to provide a practical means ofreinforcing a roadbed or an embankment to keep the gravel or otherfiller put on a roadbed from being washed away or chuck holes beingformed in it by trafiic.

It may be used on embankments as a reinforcement for the dirt and sodand also may be used to prevent washouts and keep the embankment intact.Heretofore it has been necessary to put stakes in the embankment withboards running from stake to stake for holding the sod and soil inplace, which has never been satisfactory.

The construction of this reinforcement is such that it will preventlateral or longitudinal displacement ofthe road material, therebypreserving an even and smooth contour of the wearing surface of theroadway. Also a uniform depression can be made in a roadway for thepurpose of containing and running water to a given point, which cannotbe done under the present practice in road building.

This construction is especially adapted for use in concrete roadbeds asit prevents the longitudinal cracking in the wearing surface which isexperienced in the present methods of building concrete and cementroads.

In the drawings Figure 1 is a plan view of a roadbed with a portionbroken away, showing the formation of the reinforcing means. Fig. 2 is across section on line 22 of Fig. 1. Fig. 3 is a plan view of an e11-larged portion of the reinforcement showing the means of fastening themembers together. Fig. 4 ma cross section on line k4 of Fig. 3. Fig. 5is a vertical cross section throusrh an embankment showing thereinforcement therefor.

In Fig. 1 of the drawings there is a roadbed 10 having sides or curbs11. There are members 12 formed from sheets of metal Specification ofLetters Patent.

Patented Nov. 9, 1920. Renewed December 11, 1918. Serial No. 266,311.

preferably several inches in width bent at right angles as shown in thedrawings so as to form oblong recesses at equal intervals across theroadbed. There are a plurality of said members each similarly formed andadapted to fit together adjacent each other so as to form inclosedoblong spaces substantially as shown. However, it is not material thatthe inclosures be oblong but of any shape desired.

Running along parallel with the curb on each side of the roadbed thereis a metal strip 13 at which the ends of the strips 12 are secured bystaples 14: having flanges 15 extending at right an es on the bottomthereof and resting on the roadbed adapted to be secured thereto by thefiller. At each adjacent angle of the members 12 there is a staple 16for securing said members together and holding them rigidly in place.Said staples 16 are anchored to the roadbed by spikes 17, or the stapleitself may be driven in the ground.

Each member, before being placed in position, is independent of eachother member and therefore the reinforcement is built on the roadbed, asthe construction progresses. After the reinforcement is properly laidand secured, the filler 18 is placed over it and rolled and treated inthe usual manner. The filling material extends slightly above the uppersurface of the reinforcement so as to form a smooth roadway.

he invention may be applied to reinforcing an embankment and building upthe members as described, but in using this reinforcement forembankments 110, there is an anchor line 19 extending through saidmembers and having adiustable stops 20 on the under side of each. memberfor retaining them in a parallel position, said anchor line beingsecured to an anchor 21.

After the reinforcement is laid, dirt and sod 22- may be placed over itto form the surace so that the roots of sod forming around thereinforcement will prevent it from being washed away. which is a greatdifficulty found in the present means of securing embankments.

The invention claimed is:
